Description
Technical Field
The present invention relates to a fastening fastener used in a driving tool.
Background
A fastening fastener in which a plurality of fasteners are connected by a connecting tape can be used in various types of driving tools because a large number of fasteners can be collectively mounted on the driving tool and continuously ejected. In the coupling band for coupling the fastener, the fastener can be held stably by holding the fastener at two upper and lower positions, as described in patent document 1, for example.
Patent document 1: japanese Kokai publication Hei-3-96417
Among the above-described driving tools, there are those which can use a plurality of types of fasteners having different lengths. The connecting fastener used in such a driving tool can be used in the same tool even if the length is different by using a connecting tape conforming to the specification of the tool side. In other words, the shape of the connecting band is determined according to the specifications of the tool side, and cannot be freely changed. For example, the vertical width of the coupling tape (the distance between the upper holding portion and the lower holding portion) determines the width that can be adjusted to the feeding operation of the coupling fastener on the tool side and the discharge operation of the coupling tape, and cannot be freely changed.
Therefore, when a fastener is used in which the length of the shaft portion of the fastener (the straight portion between the fastener head portion and the tapered distal end portion, or the straight portion between the cervical tapered portion and the tapered distal end portion, the straight portion may be gently tapered) is shorter than the upper and lower widths of the coupling tape, the shaft portion of the fastener cannot be held at two upper and lower positions by the coupling tape, and there is a problem that the holding of the fastener is unstable. If the fastener cannot be stably held by the connecting belt, the fastener driven in an inclined state bends, or the connecting belt, which is separated from the fastener and spreads, is caught in the interior of the machine, and the feeding operation of the connecting fastener is not smoothly performed. In this case, a fastener which cannot be held by a predetermined coupling tape on the tool side cannot be used in the related art, and the length of the fastener which can be used by the tool is limited.
Disclosure of Invention
Therefore, an object of the present invention is to provide a fastening fastener capable of stably supporting a short fastener even when the width of a fastening tape (fastening portion) is specified on the tool side, and thereby capable of using the short fastener without changing the specification on the tool side.
The present invention has been made to solve the above problems, and has the following features.

(5) The invention described in (1) to (4) is characterized in that, in addition to the characteristic feature of the invention described in any one of (1) to (4), the connecting portion is formed by bending a single long piece, in which the first holding portion, the second holding portion, and a band-like portion connecting the first holding portion and the second holding portion are formed on the same plane, the fastener includes a shaft portion provided between the head portion and the distal end portion, and a length of the shaft portion is shorter than a length of the band-like portion as viewed in an axial direction of the fastener.
(6) In addition to the feature of the invention described in (5), the fastener is characterized in that the shaft portion includes a stepped portion formed so that an outer diameter of the distal end portion side is smaller than an outer diameter of the head portion side, and the stepped portion faces an upper edge portion of the attachment portion.
(7) In addition to the features of the invention described in any one of (1) to (6), the invention described in the above is characterized in that the mounting portion includes a flange portion that protrudes in the outer circumferential direction below the second holding portion.
(8) In addition to the feature of the invention described in any one of (1) to (7), the invention described above is characterized in that the attachment portion has a retaining shape for preventing detachment of the second holding portion.
(9) In addition to the feature of the invention described in (8), the retaining shape is a tapered shape having a gradually increasing diameter toward the distal end side of the fastener.
(10) In addition to the feature of the invention described in (8), the retaining shape is a stepped shape or a concave shape in a circumferential groove shape formed by increasing the diameter of the distal end side of the fastener.
(11) In addition to the feature of the invention described in (8), the retaining shape is a bulging shape in which a head side of the fastener is bulged in an outer circumferential direction or a large diameter shape formed by making a head side of the fastener large in diameter.
Effects of the invention
(1) As described above, the present invention includes: a plurality of fasteners each having a head portion formed on one end side and a tapered tip portion formed on the other end side; a sheet-shaped coupling portion that couples the plurality of fasteners in a parallel direction; and an attachment portion that is separate from the connection portion and is attached to the fastener so as to cover at least a part of the distal end portion, the connection portion including: a first holding portion that holds the head side of the fastener; and a second holding portion that holds at least a part of a peripheral surface of the mounting portion. According to this configuration, since the fastener can be held by the second holding portion by extending the attachment portion, even when the width of the connection portion is defined on the tool side, the fastener can be stably supported regardless of the length of the fastener.
Further, since the attachment portion is a member different from the connection portion, the attachment portion is not pulled by the connection portion and does not tilt when the attachment portion is detached from the connection portion. This prevents the fastener from being bent obliquely. Further, there is no case where energy is lost to cut the connection portion.
Further, by using the mounting portion which is more stable in dimensional accuracy than the metal fastener, the size of the mounting portion can be made appropriate to the size of the second holding portion, and the holding force of the second holding portion to the fastener via the mounting portion can be increased.
Further, since the diameter of the toe side (distal end side) of the fastener is increased by attaching the attachment portion to the fastener, the fastener can be prevented from falling down in the injection path during driving. This stabilizes the fastener driving posture and prevents buckling.
In the invention described in (2), as described above, the diameter of the second holding hole provided in the second holding portion and holding the attachment portion is larger than the diameter of the first holding hole provided in the first holding portion and holding the head portion side of the fastener. According to this configuration, the shaft portion of the fastener is held by the first holding hole having a relatively small diameter, and the mounting portion is held by the second holding hole having a relatively large diameter, so that the fastener can be firmly held even in the lower portion where the mounting portion is thickened.
In the invention described in (3), as described above, the opening width of the opening edge portion of the second holding hole provided in the second holding portion and holding the mounting portion is larger than the opening width of the opening edge portion of the first holding hole provided in the first holding portion and holding the head portion side of the fastener. According to this configuration, when the fastener is loaded into the connection portion, the shaft portion of the fastener is loaded and held in the first holding hole having a relatively small opening width at the opening edge portion, and the mounting portion is loaded and held in the second holding hole having a relatively large opening width at the opening edge portion, so that the fastener can be loaded and held naturally even in a lower portion where the mounting portion is widened, and the assembly performance is good. Further, since the opening width of the opening edge portion of the second holding hole is large when the fastener is driven, the fastener can be smoothly detached from the coupling portion.
In the invention described in (4), as described above, the fastener includes the shaft portion provided between the head portion and the distal end portion, and the second holding portion holds the attachment portion at a position overlapping with the tapered distal end portion of the fastener or at a position not overlapping with the fastener. According to this configuration, even if the second holding portion reaches a short fastener such as a position overlapping with the tip end portion of the fastener or a position not overlapping with the fastener, the short fastener is extended by the mounting portion and held by the second holding portion, so that it is possible to use a short fastener which has been limited by the specifications on the tool side in the past, and even if the short fastener is held stably, the driving posture is stable, and therefore, it is possible to prevent buckling during driving.
In the invention described in (5), as described above, the length of the shaft portion is shorter than the length of the band-shaped portion when viewed in the axial direction of the fastener. According to this configuration, even in a short fastener in which the length of the shaft portion is shorter than the length of the band portion, the second holding portion holds the short fastener by extending the short fastener through the mounting portion, and therefore the upper and lower portions of the shaft portion of the fastener can be reliably held.
In the invention described in (6), as described above, the fastener includes the step portion formed in the shaft portion so that the outer diameter of the step portion on the distal end portion side is smaller than the outer diameter of the head portion side, and faces the upper edge portion of the attachment portion. According to this configuration, since the position of the mounting portion is determined by the stepped portion when the mounting portion is mounted to the fastener, it is possible to avoid the problem that the mounting portion is too shallow or too deep with respect to the mounting position of the fastener.
In the invention described in (7), as described above, the mounting portion includes the flange portion that protrudes in the outer circumferential direction below the second holding portion. According to this configuration, since the flange portion prevents the second holding portion from coming off, the second holding portion can be prevented from coming off the mounting portion.
Further, since the flange portion is provided, the diameter of the toe side of the fastener is increased, and therefore, the effect of preventing the fastener from falling down in the injection path can be improved during driving. This stabilizes the fastener driving posture and prevents buckling.
In the invention described in (8), as described above, the mounting portion has a retaining shape for preventing the second holding portion from coming off. According to this configuration, the second holding portion can be prevented from coming off by the retaining shape, and therefore, the second holding portion can be prevented from coming off the mounting portion.
When the retaining shape is provided to the fastener, there is a problem that the penetration resistance of the fastener increases or the fastener is easily bent, but such a problem does not occur by providing the retaining shape to the mounting portion.

Detailed Description
The fastening tool 10 according to the present embodiment will be described with reference to the drawings.
As shown in fig. 1, the fastening fastener 10 of the present embodiment is configured to be able to continuously discharge a large number of fasteners 11 by connecting a plurality of fasteners 11 with a connecting band 20 (connecting portion) and collectively attaching the fasteners 11 to a driving tool. Although not particularly shown, the driving tool includes a box for storing the fastening tool 10, and a conveying mechanism for conveying the fastening tool 10 stored in the box to the tip of the tool body. The feeding mechanism feeds the connected fasteners 10 one by one in conjunction with the driving operation, and thereby mounts the fastener 11 connected to the row head of the fastener 10 on the ejection path 40 provided at the tip end of the tool body. The fastener 11 thus installed on the ejection path 40 is driven by the driver 41 operated by the striking mechanism of the driver tool. The fastener 11 driven by the driver 41 is ejected from an ejection port provided at the tip end of the tool body through an ejection path 40.
The fastening fastener 10 of the present embodiment connects the fastening members 11 in parallel (in the parallel direction) so that a line connecting the centers of the fastening members 11 becomes a straight line. Thereby, the fastening fastener 10 is formed in a linear band shape.
The fastener 11 of the present embodiment is, for example, a concrete pin to be driven into concrete, a wall panel member, or the like, and includes, as shown in fig. 2(a), a head portion 12, a neck tapered portion 13 continuous with the head portion 12, a shaft portion 14 continuous with the neck tapered portion 13, and a tapered tip portion 15 continuous with the shaft portion 14. The head 12 is a disk-shaped portion that receives the driving of the driver 41. The neck taper portion 13 is a portion for smoothly connecting the head portion 12 and the shaft portion 14 and gradually reducing in diameter in a direction from the head portion 12 toward the shaft portion 14. The shaft portion 14 is a portion formed in a cylindrical shape and generating a pull-out resistance when driven into a workpiece. The tip end portion 15 is formed in a shape that is tapered and pricked toward a workpiece. In the present embodiment, the tip end portion 15 is formed in a shell shape.
The fastener 11 may have a shape including a head portion, a shaft portion having a gentle tapered shape continuous with the head portion (a tapered portion continuous with the head portion may be provided between the head portion and the shaft portion), and a tapered distal end portion continuous with the shaft portion.
In the shaft portion 14 of the fastener 11 of the present embodiment, a stepped portion 14a for reducing penetration resistance is continuously formed. Therefore, the diameter of the shaft portion 14 is smaller than the diameter of the straight portion on the head portion 12 side of the stepped portion 14a than the diameter of the straight portion on the tip portion 15 side of the stepped portion 14 a.
A cylindrical member 30 is attached to the shaft portion 14 of the fastener 11 as a cylindrical member (attachment portion). The cylindrical member 30 is formed of aluminum, synthetic resin, or the like, and includes a cylindrical portion 31 and a flange portion 33 formed to protrude from an opening edge of the cylindrical portion 31, as shown in fig. 4.
The flange portion 33 may be provided at a position other than the opening edge as long as it projects in the outer circumferential direction below the lower holding portion 23. For example, the cylindrical portion 31 may be formed to protrude in the radial direction on the outer circumferential surface thereof.
The flange 33 may be formed separately from the cylindrical portion 31. The shape of the flange portion 33 is not limited to the circular shape shown in fig. 4(a), and may be any shape as long as the outer periphery thereof is on a cylindrical locus. For example, the shape may be a polygonal shape, a rectangular shape having a cutout, or the like. The shape of the cylindrical member 30 is not limited to a circular shape, and may be a cylindrical shape having an inner circumference on a cylindrical locus. For example, the shaft portion 14 may be a cylindrical member having a polygonal shape or a rectangular shape having a cutout portion and covering at least a part thereof.
The inner diameter of the cylindrical portion 31 is formed to be large enough to press-fit the shaft portion 14 of the fastener 11 (closer to the distal end portion 15 side than the stepped portion 14 a), and the cylindrical member 30 can be attached to the fastener 11 by inserting the distal end portion 15 of the fastener 11 into the cylindrical portion 31. In the present embodiment, as shown in fig. 2(a), the fastener 11 can be inserted into the upper edge portion 32 of the cylindrical member 30 to a position facing the stepped portion 14a, and the insertion position of the cylindrical member 30 with respect to the fastener 11 can be determined by the stepped portion 14a, so that the assembling property is good.
The coupling band 20 for coupling the fasteners 11 is a sheet-like member as shown in fig. 3, and is made of synthetic resin in the present embodiment. Although the length of the connecting band 20 is shown as short in the drawings, the actual connecting band 20 is formed of 1 long piece continuous in the same shape in the vertical direction of fig. 3 (a).
The connecting belt 20 includes: an upper holding portion 22 (first holding portion) for holding the head 12 side of the fastener 11; a lower holding portion 23 (second holding portion) for holding the cylindrical member 30 attached to the fastener 11; and a belt-shaped portion 21 connecting the upper holding portion 22 and the lower holding portion 23. The upper holding portions 22 and the lower holding portions 23 are provided in the same number in correspondence with each other, and 1 fastener 11 is held by a pair of the upper holding portion 22 and the lower holding portion 23. The belt-shaped portion 21 extends in the longitudinal direction so as to connect all of the upper holding portion 22 and the lower holding portion 23.
The connecting band 20 has an upper holding portion 22, a lower holding portion 23, and a band-shaped portion 21 formed on the same plane, and has bending grooves 20a formed between the upper holding portion 22 and the band-shaped portion 21 and between the lower holding portion 23 and the band-shaped portion 21. By bending the connecting band 20 along the bending groove 20a, as shown in fig. 2(a), the connecting band 20 formed by 1 long piece is deformed intoThe font holds the fastener 11.
As shown in fig. 2(a), the upper holding portion 22 holds the uppermost portion of the shaft portion 14 of the fastener 11. As shown in fig. 3(a), the upper holding portion 22 includes: an upper slit 22a having a width narrower than the maximum diameter of the shaft portion 14 of the fastener 11; an upper holding hole 22b (first holding hole) provided on the back side of the upper slit 22 a. The diameter of the upper holding hole 22b is larger than the maximum diameter of the shaft portion 14 of the fastener 11. The upper slit 22a is provided at an opening edge of the upper holding hole 22b, and communicates with the upper holding hole 22 b.
As shown in fig. 2(a), the lower holding portion 23 holds the cylindrical portion 31 of the cylindrical member 30. The lower holding portion 23 may be configured to hold at least a part of the circumferential surface of the cylindrical member 30. As shown in fig. 3(a), the lower holding portion 23 includes: a lower slit 23a having a width smaller than the diameter of the cylindrical portion 31 of the cylindrical member 30; and a lower holding hole 23b (second holding hole) provided on the back side of the lower slit 23 a. The diameter of the lower holding hole 23b is larger than the diameter of the cylindrical portion 31 of the cylindrical member 30. The lower slit 23a is provided at an opening edge of the lower holding hole 23b and communicates with the lower holding hole 23 b.
At this time, a width DW1 of the lower slit 23a (opening width of the opening edge of the lower holding hole 23 b) is formed larger than a width UW1 of the upper slit 22a (opening width of the opening edge of the upper holding hole 22 b), and a diameter DW2 of the lower holding hole 23b is formed larger than a diameter UW2 of the upper holding hole 22 b.
By forming in this way, the lower portion of the fastener 11 corresponding to the amount of thickening of the mounting cylindrical member 30, and the inner diameter of the lower holding hole 23b becomes large, the fastener 11 can be stably held.
When the fastener 11 is loaded into the connecting band 20, the shaft portion 14 of the fastener 11 is loaded into the upper holding hole 22b through the upper slit 22a, and the cylindrical member 30 is loaded into the lower holding hole 23b through the lower slit 23 a. At this time, the width DW1 of the lower slit 23a becomes larger according to the lower portion of the fastener 11, which becomes thicker by the amount of the cylindrical member 30 to be attached, so that the fastener 11 can be packed and held naturally, and the assembling property is good.
Further, since the width DW1 of the lower slit 23a is large when the fastener 11 is driven, the fastener 11 can be smoothly detached from the connecting band 20.
However, as shown in fig. 3, the belt-shaped portion 21 of the connecting band 20 has the feeding holes 21a formed at the same interval as the holding interval of the fasteners 11. The transmission hole 21a is a hole for use in a transmission mechanism of a driving tool. That is, the feed claw of the feed mechanism engages with the feed hole 21a and operates, thereby sequentially feeding the fasteners 11 to the ejection path 40. The width of the band-shaped portion 21 having the transmission hole 21a (the length h1 of the band-shaped portion 21 as viewed in the axial direction of the fastener 11, see fig. 2(a)) is defined by a driver, and cannot be easily changed. For example, if the length H1 of the belt-like portion 21 is shortened, the conveyance mechanism cannot normally perform the conveyance operation. Thus, the length H1 of the band-shaped portion 21 cannot be changed, but the length H1 of the band-shaped portion 21 cannot be shortened in the conventional structure, so that there is a problem that the fastener 11 cannot be held short by the connecting band 20.
For example, in the present embodiment, as shown in fig. 2(a), when the fastener 11 is viewed in the axial direction, the length H2 of the shaft portion 14 of the fastener 11 is shorter than the length H1 of the band-shaped portion 21 of the coupling band 20.
Therefore, the lower holding portion 23 comes to a position overlapping with the tip end portion 15 of the fastener 11. In the conventional structure, when the fastener 11 is held in such a short length, as shown in fig. 2(b), the lower holding portion 23 may come off from the distal end portion 15 of the fastener 11, and the fastener 11 cannot be held reliably. In this regard, according to the present embodiment, since the cylindrical member 30 is attached to the fastener 11 and the lower holding portion 23 holds the cylindrical member 30, the upper and lower portions of the fastener 11 can be reliably held. This makes it possible to use a short fastener 11 that has been limited by the specifications on the tool side, and to prevent bending of the fastener 11 during driving because the driving posture of the fastener is stable.
In the present embodiment, as shown in fig. 5(a), when the fastener 11 is driven by the driver 41 in the injection path 40 of the driving tool, the fastener 11 moves in the injection path 40 in a state where the cylindrical member 30 is attached to the toe of the fastener 11. Therefore, the inclination of the fastener 11 can be suppressed. In the case where the cylindrical member 30 is not provided, as shown in fig. 5(b), the fastener 11 is driven obliquely in the injection path 40, which causes bending of the fastener 11. In this way, the fastening fastener 10 of the present embodiment can prevent bending during driving by attaching the cylindrical member 30 to the toe (the distal end portion 15 side) of the fastener 11.
In the present embodiment, since the cylindrical member 30 is provided separately from the connecting band 20, it is not necessary to separate the cylindrical member 30 from the connecting band 20 when driving the fastener 11. Therefore, when the fastener 11 is driven by the driver 41 in the injection path 40 of the driving tool, the cylindrical member 30 is separated from the connecting band 20 as shown in fig. 6(a) to (d), but the cylindrical member 30 is not inclined by being pulled by the connecting band 20. This can prevent the fastener 11 from being bent obliquely. Further, there is no possibility that energy is lost to cut the connecting tape 20.
When the cylindrical member 30 is provided as a part of the connecting band 20, as shown in fig. 7(a) to (c), the cylindrical member 30 is pulled by the connecting band 20 and inclined when the cylindrical member 30 is separated from the connecting band 20. Therefore, the fastener 11 may be bent obliquely. Further, energy loss occurs to cut the connecting tape 20. In this regard, if the coupling band 20 and the cylindrical member 30 are separate bodies as in the present embodiment, such a problem does not occur.
In the above-described embodiment, the example in which the lower holding portion 23 holds the cylindrical member 30 at a position overlapping the distal end portion 15 of the fastener 11 when viewed from the side surface direction of the fastener 11 is described. In other words, the lower holding portion 23 holds the cylindrical member 30 at a position where the leading end portion 15 of the fastener 11 reaches the lower holding portion 23 in the axial direction of the fastener 11. However, without being limited thereto, the lower holding portion 23 may hold the cylindrical member 30 at a position not overlapping with the fastener 11 as shown in fig. 8 (a). In other words, the lower holding portion 23 holds the cylindrical member 30 at a position where the tip end portion 15 of the fastener 11 does not reach the lower holding portion 23 in the axial direction of the fastener 11. Even in the case of using such a very short fastener 11, the fastener 11 can be stably held by extending the fastener 11 by the cylindrical member 30.
As shown in fig. 8(b), the flange portion 33 of the cylindrical member 30 may be disposed so as to be able to contact the lower portion of the lower holding portion 23. In this way, the flange portion 33 can suppress expansion of the lower holding portion 23, and therefore, the lower holding portion 23 can be prevented from coming off the cylindrical member 30.
In the above-described embodiment, the fastener 11 has been described by taking a concrete pin as an example, but the invention is not limited thereto. Nails may also be used as fasteners 11, as shown in fig. 9(a), for example. Further, as shown in fig. 9(b), a screw may also be used as the fastener 11.
In the above-described embodiment, the flange portion 33 is provided on the cylindrical member 30, but the present invention is not limited to this, and as shown in fig. 10(a), the flange portion 33 may not be provided on the cylindrical member 30. As shown in fig. 10(b) and (c), a long fastener 11 may be used.
As shown in fig. 11, the cylindrical member 30 may be provided with a retaining shape for preventing the lower holding portion 23 from coming off.
For example, as shown in fig. 11(a), the cylindrical portion 31 of the cylindrical member 30 may be formed into a tapered shape 34 having a gradually larger diameter toward the distal end, and the tapered shape 34 may be held by the lower holding portion 23, thereby forming a retaining shape for preventing the lower holding portion 23 from coming off. In such a configuration, in addition to preventing the lower holding portion 23 from coming off, the insertion position of the lower holding portion 23 of the coupling band 20 can be determined by the taper shape 34 when the fastener 11 is loaded into the coupling band 20, and therefore, the assembling property can be improved. Further, since the cylindrical member 30 having the tapered shape 34 is directly separated from the lower holding portion 23 when the fastener 11 is driven, the fastener 11 can be smoothly separated from the connecting band 20.
As shown in fig. 11(b), a stepped shape 35 having a large diameter on the distal end side may be formed in the cylindrical portion 31 of the cylindrical member 30, and the lower holding portion 23 may be engaged with the stepped shape 35 to form a retaining shape for preventing the lower holding portion 23 from coming off. In such a configuration, in addition to preventing the lower holding portion 23 from coming off, the insertion position of the lower holding portion 23 of the coupling band 20 can be determined by the stepped shape 35 when the fastener 11 is loaded into the coupling band 20, and therefore, the assembling property can be improved.
As shown in fig. 11(c), a recessed shape 36 may be formed in the cylindrical portion 31 of the cylindrical member 30 in a circumferential groove shape, and the lower holding portion 23 may be engaged with the recessed shape 36 to form a retaining shape for preventing the lower holding portion 23 from coming off. In such a configuration, in addition to preventing the lower holding portion 23 from coming off, the insertion position of the lower holding portion 23 of the coupling band 20 can be determined by the concave shape 36 when the fastener 11 is loaded into the coupling band 20, and therefore, the assembling property can be improved.
As shown in fig. 11(d), a bulging shape 37 bulging in the outer circumferential direction may be provided on the opposite side of the distal end of the cylindrical portion 31 of the cylindrical member 30, and the lower holding portion 23 may be engaged with the bulging shape 37 to form a coming-off prevention shape for preventing the lower holding portion 23 from coming off. In such a configuration, in addition to preventing the detachment of the lower holding portion 23, the insertion position of the lower holding portion 23 of the coupling band 20 can be determined by the bulging shape 37 when the fastener 11 is loaded into the coupling band 20, and therefore, the assembling property can be improved.
As shown in fig. 11(e), the cylindrical member 30 may have a large diameter 38 formed by increasing the diameter of the side opposite to the distal end of the cylindrical portion 31, and the large diameter 38 may be held by the lower holding portion 23, thereby forming a retaining shape for preventing the lower holding portion 23 from coming off. In such a configuration, in addition to preventing the lower holding portion 23 from coming off, the insertion position of the lower holding portion 23 of the coupling band 20 can be determined by the large diameter shape 38 when the fastener 11 is loaded into the coupling band 20, and therefore, the assembling property can be improved.
As shown in fig. 12, a stepped portion 39 may be provided in the cylindrical portion 31 of the cylindrical member 30. By providing the step portion 39, the distal end side of the step portion 39 is formed to have a larger diameter than the rear end side of the step portion 39. The step portion 39 is disposed on the toe side (the distal end portion 15 side) of the fastener 11 with respect to the lower holding portion 23 so as not to come into contact with the lower holding portion 23. In such a configuration, as in the case of the embodiment shown in fig. 11(b), the step portion 39 can suppress the expansion of the lower holding portion 23, and the lower holding portion 23 can be configured to have a retaining shape for preventing the detachment.
In the example shown in fig. 12, the step portion 39 is formed by a corner portion having a right angle in cross section. Since the lower holding portion 23 is easily caught by forming the corner portion of the stepped portion 39 at a right angle in this way, the effect of preventing the expansion of the lower holding portion 23 can be enhanced. However, the corner of the step 39 is not limited to a right angle, and may be a rounded shape as small as possible.
As described above, according to the present embodiment, the cylindrical member 30 attached to the fastener 11 is provided, and the connecting band 20 includes: an upper holding portion 22 for holding the head 12 side of the fastener 11; and a lower holding portion 23 for holding the cylindrical member 30 attached to the fastener 11. According to such a configuration, since the fastener 11 can be held by the lower holding portion 23 by extending the cylindrical member 30, even when the width of the connecting band 20 is predetermined on the tool side, the fastener 11 can be stably supported regardless of the length of the fastener 11.
Further, since the cylindrical member 30 is a member different from the connecting belt 20, when the cylindrical member 30 is detached from the connecting belt 20, the cylindrical member 30 is not pulled by the connecting belt 20 and does not tilt. This can prevent the fastener 11 from being bent obliquely. Further, there is no possibility that energy is lost to cut the connecting tape 20.
Further, by using the cylindrical member 30 whose dimensional accuracy is more stable than the metal fastener 11, the size of the cylindrical member 30 can be made to be suitable for the size of the lower holding portion 23, and the holding force of the lower holding portion 23 with respect to the fastener 11 via the cylindrical member 30 can be increased.
Further, since the diameter of the toe side (the distal end portion 15 side) of the fastener 11 is increased by attaching the cylindrical member 30 to the fastener 11, the fastener 11 can be prevented from falling down in the injection path 40 during driving. This stabilizes the driving posture of the fastener 11 and prevents the fastener from bending.
Further, the diameter of the lower holding hole 23b provided in the lower holding portion 23 for holding the cylindrical member 30 is larger than the diameter of the upper holding hole 22b provided in the upper holding portion 22 for holding the head 12 side of the fastener 11. According to such a configuration, the shaft portion 14 of the fastener 11 is held by the upper holding hole 22b having a relatively small diameter, and the cylindrical member 30 is held by the lower holding hole 23b having a relatively large diameter, so that the fastener 11 can be firmly held even in the lower portion where the cylindrical member 30 is thickened.
Further, the lower holding portion 23 holds the cylindrical member 30 at a position overlapping with the tapered distal end portion 15 of the fastener 11 or a position not overlapping with the fastener 11. According to such a configuration, even if the short fastener 11 is reached where the lower holding portion 23 overlaps the distal end portion 15 of the fastener 11 or where the short fastener 11 does not overlap, the lower holding portion 23 is held by extending the short fastener 11 by the cylindrical member 30, and therefore the fastener 11 can be stably held.
Further, the length H2 of the shaft portion 14 is shorter than the length H1 of the band-shaped portion 21 as viewed in the axial direction of the fastener 11. According to such a configuration, even in the case of a short fastener 11 in which the length H2 of the shaft portion 14 is shorter than the length H1 of the band-shaped portion 21, the short fastener 11 is extended by the cylindrical member 30 and the lower holding portion 23 is held, so that the fastener 11 can be stably held.
The cylindrical member 30 includes a flange portion 33, and the flange portion 33 is formed to face a lower portion of the lower holding portion 23 and to protrude in a radial direction of the outer periphery of the cylindrical member 30. According to such a configuration, the flange portion 33 prevents the lower holding portion 23 from coming off, and therefore the lower holding portion 23 can be prevented from coming off the cylindrical member 30.
Further, since the diameter of the toe side of the fastener 11 is increased by providing the flange portion 33, the effect of preventing the fastener 11 from falling down in the injection path 40 during driving can be improved. This stabilizes the driving posture of the fastener 11 and prevents the fastener from bending.
The fastener 11 includes a stepped portion 14a in the shaft portion 14, and the stepped portion 14a is formed so that the outer diameter on the side of the distal end 15 is smaller than the outer diameter on the side of the head portion 12, and faces the upper edge portion 32 of the cylindrical member 30. According to such a configuration, since the position of the cylindrical member 30 is determined by the stepped portion 14a when the cylindrical member 30 is attached to the fastener 11, it is possible to avoid the problem that the attachment position of the cylindrical member 30 to the fastener 11 is too shallow or too deep.
The cylindrical member 30 has a coming-off prevention shape for preventing the lower holding portion 23 from coming off. According to such a configuration, since the separation of the lower holding portion 23 is prevented by the retaining shape, the separation of the lower holding portion 23 from the cylindrical member 30 can be prevented.
When the retaining shape is provided in the fastener 11, there is a problem that the insertion resistance of the fastener 11 increases or the fastener 11 is easily bent, but such a problem does not occur by providing the cylindrical member 30 with the retaining shape.
